Chapter 242 Four Pillars Of Pure Yin
- The ancestors used the Book of Changes to explore the mysteries of the heavens and the earth, using year, month, day, and hour of the sexagenary cycle (stems-and-branches) to arrange the Four Pillars of Destiny (eight characters), namely, the year pillar, the month pillar, the day pillar, and the hour pillar.
- Among the stems-and-branches, odd numbers referred to Yang and even numbers referred to Yin. Having all even numbers for all four pillars were simply known as Four Pillars of Pure Yin.
- It was rare to see a pure Yin or a pure Yang, and they were ill-fated.
